DDR3 Registered DIMM DDR3 Registered DIMM is high-speed, low power memory module that use DDR3 SDRAM in FBGA package, 1 pcs register in TFBGA package and a 2048 bits serial EEPROM on a 240-pin printed circuit board. DDR3 Registered DIMM is a Dual In-Line Memory Module and is intended for mounting into 240-pin edge connector sockets. Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on both edges of DQS. Range of operation frequencies, programmable latencies allow the same device to be useful for a variety of high bandwidth, high performance memory system applications. Features Pin Identification RoHS compliant products. JEDEC standard 1.5V ± 0.075V Power supply VDDQ=1.5V ± 0.075V Clock Freq: 533MHZ for 1066Mb/s/Pin 667MHZ for 1333Mb/s/Pin.
